Hi Aryeh,
I think IE does not support this property. My suggestion is go with jQuery.

To use jquery is your best option:
$('table tr td a').each(function(){
if ( $(this).attr('id').match(/foo/g) ) {
// do something with it
}
});
Mcnute, can you tell me.
in your jquery code, where do I use the table_node variable?
(this is the ONLY table in the document I want to search in).
Thanks.

if it is the only table in the page, then my code snippet will do. Otherwise give your specific table an id.
var table = $('#id_of_the_table').find('a');
table.each(function(){
if ( $(this).attr('id').match(/foo/g) ) {
// do something with it
}
});
you can give whatever id you want, unless it begins with an alpha value from a-z. id's like 1-item are not allowed since it starts with a number.
So it can be $('#table_node'), yes.

I mean, what if the table_node is DOM element?
retrieved somehow (it has NOT an id property).
e.g. table_node = some_element.parentNode.ch

If you know that it is the third table in the DOM, then you can do something like this:
Considering that index starts at 0 so your first is 0, second table is 1, third is 2.
Am I understanding you right there?
You seam to know which table that is. You have a varialbe with the object of the table stored in it, right? You can just use it as is:
$('table:eq(2)').find('a');
